My hybrid plansHi, I’m thinking of building a handheld burst disk hybrid which operates with a 4x mix of propane and air. Here are the specs: schedule 40 steel pipe construction, 3” x 16” chamber, 1 1/2” x 40” barrel, spark plug and modified arc lighter ignition (or nichrome wire, a 9 volt, and a toggle switch). Can I fire this without a stand without falling over? Or do I need to make a stand for it? I’m considering a muzzle brake because it might actually help because of the amount of gasses from a hybrid (I think so anyway). I’m not a very large person (I’m 13) so the recoil might be a little much for me.
The weird thing is my only source of compressed air is a bike pump!
Re: My hybrid plansPlugging your specifications into HGDT gives us the following:
![]() 1785 ft lbs (I assumed a 1 lb projectile) of muzzle energy is less than what you would expect for a typical 12 gauge shotgun load. Here's a 13 year old kid shooting a much, much more powerful 10 gauge shotgun: ![]() If it's well supported and you lean into it properly, it shouldn't knock you over.
Re: My hybrid plansOk, thanks. I guess it wouldn’t kick much more that the dumpster cannon (a bad idea!).
